I love roasted carrots.  There is nothing simpler or more delicious.  Roasting brings out the natural sweetness of the carrots and intensifies the flavor; plus, they are so easy and quick to prepare.  
Preheat oven to 400 degrees.  Slice carrots diagonally and place them on a baking sheet.  If carrot pieces are thick, cut them in half lengthwise.  Toss with olive oil, coarse salt and pepper.  Roast until tender.  Sprinkle with dill or parsley and serve.
